Plain Water Sugar Water Salt Water Problem: Which water freezes the fastest? Plain, Sugar or Salt Water?
HYPOTHESIS If we put salt or sugar in water it will freeze faster than a plain cup of water. Plain Sugar Salt
HYPOTHESIS The Vote Plain Salt Sugar 3 for plain water 4 for salt water 11 for sugar water
Plain Sugar Salt Variables Independent Variable- The water was changed by adding different substances. Dependent Variable- The element that was changed by sugar or salt.
Materials 2. Food Coloring 3. Sugar 4. Salt 1. Water 5.Clear cups 6. Measuring Cups
Procedure 1.Collect Materials. 2.Pour a water into each cup. 3.Pour 1/ 8 cup of sugar in one. 4.Pour 1/8 cup of salt in another one. 5. Leave one cup of water plain. 6. Sit each cup in the freezer and watch which one freezes faster!
Results The sugar water froze faster than the plain and salty water. However, the salty water was the least frozen one of all.
Plain WaterHalf Frozen Sugar WaterFully Frozen Salt Water1/3 Frozen
Data Graph Plain water froze halfway. Sugar water froze all the way. Salt water did not freeze solid. Still partly a liquid.
Conclusion We concluded that different substances can make a difference in how fast water freezes. The sugar water froze the fastest.
